Many medicines in use today cause dry mouth, and any dentist will tell you that dry mouth is the root cause of an epidemic of cavities.
One of the alternative treatments for dry mouth is glycerin. This is used as a mouth wash to moisten the gims and teeth for a long period, especially at night, helping to prevent cavities due to dry mouth.
Some colloidal silver may be mixed with the glycerin to actively destroy bacteria and fungus in the mouth.
Frontier vegetable glycerin is made form the palm tree, which is a rich source of so many healing compounds. Food-grade glycerin is completely safe to out in the mouth or to consume.
